From passenger cars to commercial fleets, rail, and marine vessels, mobility platforms combine electrification, hybrid drivetrains, and combustion systems under tighter packaging and higher performance demands than ever. KOENIG EXPANDER®, KOENIG RESTRICTOR®, and KOENIG CHECK VALVE® components seal access bores and control fluid flow directly in the component — supporting the safety, durability, and efficiency targets of every mobility platform.
Automotive
Sealing and flow control for electric, hybrid, and combustion vehicle systems — battery and motor housings, transmissions, cooling, braking, and steering systems.
Marine
Corrosion-resistant sealing and flow control for propulsion, hydraulic steering, and cooling systems operating in harsh marine environments.
Rail
Dependable sealing and flow control for braking, suspension, and hydraulic systems in rolling stock, built for long service intervals and high duty cycles.
Commercial Vehicle
Rugged components for the hydraulic and drivetrain systems in trucks, buses, and heavy-duty vehicles operating under continuous load.
